ANCHOR FOR ROOF-SHEETS.

Specification of Letters Patent.

Patented May 22, 1917.

' Application filed October 21, 1916. Serial No. 126,842.

To all whom itm'ag concern:

Be it known that 1, JOHN T. CRALLEY, a citizen ofthe United States, anda resident of the city of Chicago, in the county of Cook 5 and State ofIllinois, have invented a new and useful Improvement in Anchors forRoof-Sheets, of which the followingis a specification.

roofs for railway cars of the type which'has roof sheets pivotallysecured in place, andis an improvement on the ridge construction shownand describedin C. G. Murphy Patent No. 1,133,493, dated March 30, 1915.

The objects of the invention are to provide for securing the roof sheetsinplace so that they are free to move about to a limited extent, and tolocate the securing means heneath the roof sheets instead of on top ofthem. I

The invention consists in positioning the roof sheets and holding themdown upon the roof substructure at the ridge by means of anchors whichare pivoted to the substructure at the ridge line, and which fit underthe ends of the roof sheets and are hooked over their ridge flanges.There is a separate anchor for each roof sheet, thereby permitting theroof sheets to move independ- Further objects and particulars of the invention appear in connection with the following description of the roofconstruction shown in the accompanying drawings; and

I what the invention consists in is further stated in the appendedclaims.

y In the drawings, wherein the same refer ence characters designate thesame parts in the several views,

Figure 1 is a plan view of a ridge portion ofan outside metal car roof,showing the pivots and anchors for securing two roof sheets; I

I Fig. 2 is a cross-section of the same on the line 2-2 in Fig. ,1; and

Fig. 3 is a perspective view of a pair of roof sheet anchors in place onthe substructure ready to receive the roof sheets.

For purpose of illustration, the invention is shown applied to a carhaving a wooden ridge pole 11 and roof sheathing boards 12. The roofsheets 13 have pivot bosses ,14'

- "This invention relates to outside metal ently of each other'upon thesubstructure struclr up-in them near their ridge ends, and

upstanding flanges 15 along their ridge ends. The edges of the flanges15 are bent in and. turned, down over the roof sheets The roof sheetsare spaced apart at their ridgeends and the flanges 15 are covered by aninverted channel shape ridge cap 16,

which, has the lower edges of its side walls bent in and turned up underthe inturned extremities of the roof sheet flanges 15. r

The roof sheets are loosely held in place by anchor strips 17, which arearranged in pairs, one on each side of the ridge,.with

their ridge ends lapping and pivotally secured to the substructure bymeans of a bolt,

18. Each-anchor strip has a pivot boss 19 fitting under the pivot boss14; in the corresponding roof sheet, and an. upstanding flange 20 at itsridge end which is bent at its extremity over the flange 15 of the roofsheet to hold the roof sheet down on the anchor strip. This arrangementpermits the roof sheets to pivot around the pivot bosses, and permitsthe anchor strips to pivot around the bolts 18.

The invention is not restricted to the particular shape andarrangement-attire roof sheet pivot bosses, flanges and anchor stripsshown in the drawings.

' I claim the following as my invention:

1. An anchor strip for pivotally securing a roof sheet, said anchorstrip having'a pivot for the roof sheet to turn on and said anchor stripalso having means formed integral therewith for securing said anchorstrip to the roof sheet.

2. An anchor strip for pivotally securing a roof sheet, said anchorstrip having a pivot for the roof sheet to turn on and a flange adaptedto hook over the edge of the roof sheet for securing said anchor stripto the roof sheet.

3. An anchor strip for pivotally securing a roof sheet, said anchorstrip having a pivot boss formed up 1n 1t for the roof sheet to turn onand means at one edge for hooking over the edge of the roof sheetforholding a roof sheet, said anchor strip having a pivot for the roofsheet to turn on, in combination with means for pivotally securing saidan chor strip to the car, and means for securing said anchor strip tothe roof sheets, said se: curing means being located'at the ridge of thecar, and a ridge cap for covering said securing means.

6. In combination with movably supporh ed roof sheets having pivotbosses near their 10 ridge ends. a pair of anchor strips lapping attheir ridge ends and pivotally seeiired to the car through their lappingportions, said anchor strips having pivot bosses fitting the pivotbosses of said roof sheets.

Signed at Toledo, Ohio, this 17th day of October, 1916.
